IGNITING DEVICE FOR MINERS LAMPS, 84C.

SPECIFICATION forming part of Letters Patent No. 612,293, dated October 11, 1898. Application filed April 7,1898. smart. 676,789. (No model.)

T at whom it may concern.-

Be it kn own that I, CARL HEINRICH WOLF,

, manufacturer, a subject of the Emperor of into flame.

Germany, residing at Z Wickau, in the Empire of Germany, have invented a new and useful Improved Igniting Device for Miners Lamps and the Like, of which the following is a full, clear, and exact description.

This invention relates to a device for igniting miners safety-lamps which are adapted to burn benzene, oil, and other inflammable materials.

A strip of linen, cotton, or other suitable material serves as igniting material, which is impregnated with paraffin or wax and provided at equal distances with pellets of a substance which is ignited by friction on the device being operated'so that the portion of the strip beyond such ignited substance is set The projected burning strip ignites the wick of the lamp. This manner of ignition is undoubtedly safer than the socalled percussion ignition heretofore employed. There is no possibility of the flame or spark passing through the wire-net mantle when igniting the lamp, since the ignitingfiame is developed gradually, whereas by the older method of ignition, which is effected by v the explosion of a so-called amorce pill, it is possible for the flame to penetrate through the wire-gauze chimney of the miners lamp. This has been proved by some fire-damp explosions which are supposed to have been caused by the above mentioned circumstance.

The important advantages of this improved igniting device are as follows:

First. The construction is considerably simpler and stronger, so that the miner is able to ignite the extinguished lamp with safety.

Second. The various parts may be readily and quickly changed or substituted by any workman without solder or rivets being employed.

Referring to the accompanying drawings, Figure 1 is a sectional View of the igniting device. Fig. 2 is an end View, and Fig. 3 a plan view, of same. Figs. 4 to 9 represent details of the device.

a'represents the receptacle for holding the coiled igniting strip or tape 12.

o is a piece of the form shown in Fig. 4 in sectional view and plan, which is rigidly secured to the receptacle and adapted to receive the spring-rack z, separately shown in Figs. 8 and 9 in elevation and plan. For the purpose of removing this rack for cleaning or changing same it is only necessary to slightly.

whereas they cause a suitable resistance when the strip is pulled downward.

dis a rod or handle provided with a spring pivotally connected therewith, such spring having tongues e and f. (Separately shown in front and side elevation in Fig. 3.) The tongue f is provided with some teeth 9, which tear the igniting-pellets provided on the igniting-tape b, so that by the flame thus produced the strip is set into flame. The tongue f is guided with its shoulders f and f in grooves 11 t" of the socket-piece c, Fig. 6, so that the teeth are prevented from penetrating too far into the strip. The tongue e is provided at its upper end with a bent part h. On the tongues being in their most upright position this bent part passes out of the receptacle, so that in order to prevent the spring being weakened the elasticity is diminished, whereas on drawing the tongues downward the spring is strained again and contacts with the igniting-pellet. I

In order to cause ignition, the rod or handle d, together with the striker, is pulled downward, the igniting-pellet caught, and a slight pressure upward suflices to bring the burning strip out of the receptacle.

Having particularly described and ascertained the nature of this invention, I declare that what I claim, and wishto secure by Letters Patent, is-
